US stocks jumped on Tuesday as optimism that the Trump administration could move to ease lockdowns from the coronavirus outbreak overshadowed worrying earnings reports from JPMorgan and Wells Fargo.

White House adviser Larry Kudlow said President Donald Trump would make a number of announcements about reopening the US economy in the next day or two as the health crisis appeared to be ebbing, although some state governors have said the decision to restart businesses lies with them.

The Nasdaq registered a fourth straight day of gains. Among its biggest boosts was Amazon.com, which rose 5.3% to $2,283.32, a record high close.

Shares of JPMorgan Chase & Co and Wells Fargo & Co reversed early gains to end lower. Their first-quarter profits plunged, with both banks setting aside billions of dollars to cover potential loan losses from the pandemic.

The Dow Jones Industrial Average rose 558.99 points, or 2.39%, to 23,949.76, the S&P 500 gained 84.43 points, or 3.06%, to 2,846.06 and the Nasdaq Composite added 323.32 points, or 3.95%, to 8,515.74.

US stocks have recovered in the past month after slumping more than 30% from their February record highs, helped by monetary and fiscal stimulus and the early signs of a plateau in the number of coronavirus cases. The S&P 500 is still down about 16% from its Feb. 19 record closing high.

Also boosting stocks, Apple Inc shares rose 5.1% as data showed iPhone shipments to China rebounded slightly in March after crashing in February.

Volume on US exchanges was 12.01 billion shares, compared with the 14.58 billion-share average for the full session over the last 20 trading days.

Advancing issues outnumbered declining ones on the NYSE by a 3.19-to-1 ratio; on Nasdaq, a 2.54-to-1 ratio favored advancers. The S&P 500 posted eight new 52-week highs and no new lows; the Nasdaq Composite recorded 25 new highs and 12 new lows.
